“…Fazelzadeh and Jafari [15] considered active supersonic panel flutter suppression by using piezo-electric actuators in an optimal integral-feed forward LQR control scheme. Korbahti [24] employed a Proportional-Integral-Derivative (PID) Controller to suppress the flutter speed of a specially orthotropic plate of rectangular cross-section. Wang et al [50] used the eigen-vector orientation method and finite element modeling in a linear optimal (LQR) control design context to actively suppress the subsonic and supersonic flutter of panels via piezo-electric actuator layers.…”

“…Besides the active flutter control methods mentioned above, Korbahti 170 studied the active flutter control of a special orthotropic plate and designed the controller using PID control algorithm. The critical flutter aerodynamic pressure of the plate can be increased by changing the gain coefficient.…”

Flutter is a self-excited vibration under the interaction of the inertial force, aerodynamic force, and elastic force of the structure. After the flutter occurs, the aircraft structures will exhibit limit cycle oscillation, which will cause catastrophic accidents or fatigue damage to the structures. Therefore, it is of great theoretical and practical significance to study the aeroelastic characteristics and flutter control for improving the aeroelastic stability of aircraft structures. This paper reviews the recent advances in aeroelastic analysis and flutter control of wings and panel structures. The mechanism of aeroelastic flutter of wings and panels is presented. The research methods of aeroelastic flutter for different structures developed in recent years are briefly summarized. Various control strategies including the linear and nonlinear control algorithms as well as the active flutter control results of wings and panels are presented. Finally, the paper ends with conclusions, which highlight challenges of the development in aeroelastic analysis and flutter control, and provide a brief outlook on the future investigations. This study aims to present a comprehensive understanding of aeroelastic analysis and flutter control. It can also provide guidance on the design of new wings and panel structures for improving their aeroelastic stability.

“…Moon and Hwang (2005) investigated the flutter suppression of composite panels with LQR controller based on the linear and nonlinear models. Using the proportional integral derivative controller, Korbahti (2010) researched the aeroelastic flutter control of a rectangular panel in supersonic airflow. The detailed analyses on the influences of feedback control gains on the flutter bounds of the panel were carried out.…”

Aerothermoelastic flutter properties of nonlinear composite laminated panels in supersonic airflow are studied, and investigations on active flutter and aerothermal postbuckling suppression for the panels with time-dependent boundary conditions are also carried out using macro fiber composite actuator and sensor. The von Karman strain–displacement relation in conjunction with the supersonic piston theory is applied in structural modeling. Nonlinear dynamic equations of motion for the structural system are established using Hamilton’s principle and the assumed mode method. Frequency- and time-domain methods are used to investigate the aerothermoelastic characteristics and active flutter and aerothermal postbuckling suppression of the panels. Effects of aspect ratio and ply angle on the nonlinear aerothermoelastic behaviors are studied. The displacement feedback control is used to conduct the active flutter and postbuckling suppression. The nonlinear output controller consisting of a linear quadratic regulator and a nonlinear state estimator of extended Kalman filter is also used in designing the controller. Controlled vibration responses of the structural system under the two different controllers are compared. The results show that the developed linear quadratic regulator/extended Kalman filter controller is more effective than the displacement feedback control controller in flutter and postbuckling control of the panels with time-dependent boundary conditions in supersonic airflow.
